a. Determine the acceleration at the instant shown.

b. Determine the increase in speed and the normal component of acceleration at s = 2 m. At s = 0, v = 0.

c. Determine the acceleration at the instant shown. The particle has a constant speed of 2m/s.

d. Determine the normal and tangential components of acceleration at s = 0 if v = (4s + 1) m/s, where s is in meters.

e. Determine the acceleration at s =2 m if v ˙ = (2 s) m/s2, where s is in meters. At s = 0, v = 1 m/s.

f. Determine the acceleration when t = 1 s if v = (4t2 + 2) m/s, where t is in seconds.

The y-coordinate of a particle in curvilinear motion is given by y = 5.2t³ -2.6t, where y is in inches and t is in seconds. Also, the particle has an acceleration in the x-direction given by ax = 3.8t in./sec². If the velocity of the particle in the x-direction is 12.2 in./sec when't = 0, calculate the magnitudes of the velocity v and acceleration a of the particle when t = 3.8 sec. Construct v and a in your solution. Answers: When t = 3.8 sec, V = a= MI MI in./sec in./sec²
